(Specification)Standard Specification for Welded Brass Tube
Standard Specification for Welded Brass Tube
ABSTRACT
This specification establishes the requirements for round, rectangular, and square copper alloy welded tube for general engineering applications. The tubes are classified into four types: Type I tubes which are finished by passing through sizing and straightening rolls at ambient temperature; Type II tubes which are finished by sizing, straightening, and annealing; Type III tubes which are finished by cold reducing or cold drawing over a plug or mandrel; and Type IV tubes which are finished by cold drawing over a plug or mandrel and annealing, and redrawing and annealing when necessary to conform to a specified size and temper. Tubes shall be welded by any process which produces forged or fusion welds. Forged-welded tube shall be scarfed to remove both internal and external flash. Forged-welded tube to be drawn over a mandrel to produce Types III and IV may have the internal flash completely removed. Fusion-welded tube shall be mechanically worked to produce a smooth external and internal surface without the application of scarfing or other removal of the weld metal bead. Grain size and mechanical properties such as tensile strength and Rockwell hardness shall be determined. The tubes shall be subjected to mercury nitrate, expansion, flattening, and reverse bend tests for performance evaluation. Non-destructive tests such as eddy-current test, hydrostatic test, and pneumatic tests shall be done as well.
SIGNIFICANCE AND USE
For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29:

SCOPE
1.1 This specification establishes the requirements for round, rectangular, and square copper alloy welded tube for general engineering applications.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following hazard statement pertains only to the test method described in 18.2.3, 18.2.4, 18.2.6, and 18.2.7 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
